Apple and Google aren't the only tech giants exploring the brave new world of self-driving cars. Financial Times tipsters report that Sony has invested roughly $842,000 into ZMP, a Japanese autonomous vehicle startup. While it's a small start, Sony apparently has big plans -- it wants to combine its cameras with ZMP's robotics to develop "self-driving technologies." That doesn't necessarily mean you'll see a Sony-branded ride, but you could easily find the company's equipment inside cars from various marques. The move at least makes sense. Sony is already working on automotive cameras, so it's no big leap to translate that experience to hands-off transportation.
